LINES FOR VESSELS.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed April 27,1906. Renewed May 10, 1907. Serial No. 372.877.

.which the following is a specification.

My invention relates to ships and vessels, propelled by sails, or steam screw power or hand screw power and consists in the lines of construction of said ships, vessels and boats, by which the energy due to the impact of Waves against the sides of the vessel aid in the propulsion of the same, which construction will be hereinafter fully described, illustrated in the drawings, and particularly pointed out in the claims.

The ob 'ect of my invention is to utilize a part of the energy due to the impact of waves against the sides of the vessel and aid in the propulsion of the same, and it consists in providing at or near the mid-ship section of the vessel in addition to the usual counters and over-hanging stem portion, a rearwardly and outwardly presented abrupt abutment having a wave impact receiving surface of suliicient dimensions to aid in sending the vessel ahead when the waves moving in a forward direction impinges thereon. This I accomplish by the structures shown in the accompanying drawings forming a part of this application in which like letters indicate similar parts.

Figure l is a side view of the hull of a vessel designed to be primarily, propelled by steam, showing my invention of construction of lines. Fig. 2, is a bottom view of-a vessel showing my invention of construction of lines. Fig. 3, is a detail view showing a short straight bevel line in the side of a vessel. Fig. 4, is a detail view, showing a short convex bevel line in the side of a vessel. Fig. 5, is a detail view, showing a short concave bevel line in the side of a vessel.

Referring now to the drawings, A represents the hull of a vessel and B, a rearwardly and outwardly presented beveled section of the same. This beveled section, as shown in Figs. 1 and 2, is preferably located near midship, but may be located less near that point, either backward or forward. The beveled section or abutment B'mayI be of different depths, according to the size of the ship,

vessel, or boat, but in ordinary large vessels its depth is 5 or 6 feet or more.

In ordinary operation when forwardly moving waves strike the counters and overhanging stern portion they lift the vessel and send it ahead, and in addition, whenleaving the counters they impinge against the abutment B and an additional energy is thereby imparted to the vessel which drives it farther ahead. As

shown in Figs. l and 2, this beveled section should extend from the keel or near thereto and run at right angles therefrom, outward and u ward to or near to the water line on both sides of the vessel, but it may be of less extent, starting above the keel, or of greater extent, terminating above the water line. As shown in Figs. l, 2, and 3, this beveled section will run in a straight diagonal line a, inward and backward, while in Fig. 4c such line a, is convex and in Fig. 5, is concave.

The hull of a ship, vessel or boat, constructed as above described will develop a greater speed under a given propelling force, for the reason that the water flowing forward and inwardly toward the hull, such as wave-action or currents, will strike upon the bevel section and acting under the well known laws of reiiection, will develop a reaction in the direction of the hulls travel. This action is suggested by the divergent lines in Figs. 3, 4 and 5, to `which attention is called.

I am aware that it has been heretofore proposed to provide a vessel with an abutment somewhat similar to mine, in connection with aspecially constructed paddle wheel, but my device differs essentially from the same in that no wheel is used and therefore no special construction of wheel is necessary and moreover it relies on the forward motion of the im acting waves for its successful operation.

ilaving fully described my invention, what I claim and desire to secure by Letters Patent 1s;

l. The combination in a vessel having sail or screw power a hull provided with the usual counters and over-hanging stem, a wave impact receiving surface of sufficient dimensions to aid in forcing the vessel ahead when waves moving in a forward direction impinge thereon, substantially as described.

2. The combination in a vessel having sail or screw power a hull provided with the usual counters of an abrupt abutment at or near IOO the mid-ship section having a Wave impact receiving surface Jor suicient dimensions to aid in forcing the vessel ahead When Waves moving in a forward direction impinge thereon, and a keel beginning at or near said abutment and extending to the stem of said hull, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.

THEODORE R. TIMBY.
